What if you are running Windows NT/2000/XP? If your computer is ``upgraded'' from one of the operating systems on the list, you may have a legacy partition that is still FAT-based. Otherwise, you probably only have NTFS partitions. But that's okay, we'll discuss that later.
You can also find FAT partitions on floppy disks, ZIP disks and most USB flash storage devices (also called jump drives, keychain drives, flash drives, etc.). This is great, because now you can save data onto a removeable medium!
